Instrumentation for the California Extremely Large Telescope

Abstract

The Phase A study for the California Extremely Large Telescope (CELT) Project has recently been completed. As part of this exercise a working group was set-up to evolve instrumentation strategies matched to the scientific case for the CELT facility. We report here on the proposed initial instrument suite which includes not only massively multiplexed seeing-limited multi-object spectroscopy but also on plans for wide-field adaptive optics fed integral-field spectroscopy and imaging at, or approaching, CELT's diffraction limit.

We would like to thank all our colleagues who contributed to the CELT Phase A design study and in particular the members of the CELT Instrumentation Working Group (Puragra Guhathakurta, James Graham, James Larkin and Steve Vogt) who contributed much material on which this summary paper is based. KT would also like to acknowledge the assistance of Bob Weber and Sean Lin (Caltech) who created the bulk of the engineering designs for the study; optical design consultant Damien Jones (Prime Optics, Qid., Australia) and Sam Barden (NOAO) who freely shared his own ideas during the parallel GSMT study.
